UNITED STATES MARTIN WILOOX, OF SACRAMENTO, CALIFORNIA.

IMPROVEMENT IN STEAM-PUMPS.

Specification forming part. of Letters Patent No. 49,461, dated August 15, 1865.

To all 'whom it may concem.'

Be it known that I, MARTIN WILcoX, of Sacramento, in the county of Sacramento and State of California, have invented certain new and useful Improvementsin Steam-Pumps, and I do hereby declare that the following is afull and complete description of the construction and operation of the same, reference being had to the accompanying drawings, making apart of this specification, in which- Figure l is a side elevation. Fig. 2 is a vertical section. Fig. 3 is a detached section.

Like letters of reference denotelike parts in the views.

'Ihe nature of my invention consists in the peculiar arrangement ot' parts for condensing steam, exhausting itfrom the receiver, and discharging uncondensed steam and air from the pump; also, to working the steam -gate, as hereinafter described.

In Figs. l and 2, R It represent receivers; F F, iioats that work in them.

D is a pipe i'or discharging water from both the receivers, through chambers M and N, by valves@ o e.

S is the supply passage, convcyingwater through the valves e' e into the chambers MN.

C isacondenser that exhausts steam from the receivers through pipes E E.

` P P arc pipes carrying steam to and from the receivers.

lis thein gress-pipe for steam from the boiler.

gisarevolvinggate,lettingstcam alternately to and from the receivers.

o is the case inclosing the gate.

fw is a pipe for conveying cold water into the condenser, and H is a pipe for carrying the water out.

b is a discharge-valve, and a apa-rtition partially dividing the condenser.

In Fig. l, K is a ratchet-wheel placed on the shaft of the steam-gate g, and works loose on it.

J is a toothed wheel secured on the shaft c, that works the pendulum h.

t is a cylinder, communicating at its lower end with the condenser, and Works a piston to which is attached a latch, i, for operating the wheel J.

Fig. 3 represents another form of a toothed wheel, to be used in place of J when the pendulum cannot be long enough to measure the 1'ntervals of the stroke of the pump.

rIhe operation of thepumpisasfollows: The

gate being set to admit steam to either one of the receivers, it is necessarily cut oft fromthe other. the gate and passages being soarranged that while one receives the other discharges steam. Ihe steam entering the receiver at the upper end displaces water, which discharges byl means ot the pipe D through the chambers Mor N and valves e', until the oat strikes the bottom, and closes the passage into the chamber air before contained there, and also forces out-' ward the piston in the cylinder t, setting the latch l forward upon thc wheel 7s. When the expansive force of the steam in the consdenser C is spent, cold water enters through thepipe w, causing condensation in thechamber 0,.

closing the valve b, and drawing the piston in the cylindert back, thus by means of the latch Z turning thewheel k. As the wheel J is attached to k by a spring on the shaftebetween the wheels the motion of the wheel k is communicated to J bythe spring as soon as thependulum swings to the right position to alloWJ to turn. When the wheel J turns the gate turns with it, and at no other time.

The length of the pendulum is regulated to suit the length of time occupied by the alternation of tillingand dischargin gof the receiver. When a pendulum cannot be used suciently long to meet the required time of action in the receiver a modified form of toothed wheel, `as seenin Fig. 3, is used in the place ot' J.

The spaces. c between the clusters of teeth w indicate the number of positions to which the gate works, and the number of teeth in each clusterdetermines the number of vibrations the pendulum must make between the changes of the gate. The nuinber ot' teeth, and also the number ot positions of the gate, with the necessary position of steam-passages to the gate, are to be arranged to suit each part.

` The cyliudert may attach to and communi` cate with the rcceiverinsteadotI the condenser, it' desired; or a diaphragm` may be used instead ot' a cylinder and piston. is not required to be ofthe same form or pro- The condenser portion as herein shown. The partition is for the purpose of preventing the immediate contact of steam with the jets of cold water when it rst enters G. The pipe w is made to discharge beyond the partition for the same rea` son. The pressure of uncondensed steam contained in C upon the first entrance of the neXt discharge of steam interrupts the iiow of condensed Waterbei'ore the hotsteam reaches that point. Water kept standingon the upper part of C will prevent the valve b from drawing air when closed.

I do not limit the application of my invention to anyparticularnumberof receivers used in one pump, as it may be applied to any number of receivers discharging by one or moreW pipes. The pipeH is not indispensably necessary, as the condensed Water might be forced out at Il.

Vhat I clainas my improvement, and desire to secure by Letters Patent, is-4 1. The condenser G,in combination with the receivers R, for exhaustingthereceiver and discharging uncondensed steam, constructed and MARTIN W ILGOX.
